Light Adaptation in Drosophila Photoreceptors
Besides the physical limits imposed on photon absorption, the coprocessing of visual information by the phototransduction cascade and photoreceptor membrane determines the fidelity of photoreceptor signaling. We investigated the response dynamics and signaling efficiency of Drosophila photoreceptors to natural-like fluctuating light contrast stimulation and intracellular current injection when ...
متن کاملPrimary myogenic cells see the light: improved survival of transplanted myogenic cells following low energy laser irradiation.
BACKGROUND AND OBJECTIVES There is a substantial need for finding new avenues to promote muscle recovery when acute skeletal muscle loss extends beyond the natural capacity of the muscle to recover. Maintenance and regeneration of skeletal muscles depend mainly on resident stem cells known as satellite cells. Nevertheless, there are situations in which a significant loss of muscle tissue exhaus...
متن کاملTransplantation of photoreceptors to light-damaged retina.
We investigated the possibility of reconstructing light-damaged retinas by photoreceptor transplantation. The outer nuclear layer containing the photoreceptor cells was eliminated in adult albino rat retinas by exposure to constant high-level illumination. Photoreceptors for transplantation were harvested from neonatal rats using a novel isolation technique that maintained the cellular organiza...
متن کاملLight adaptation in salamander L-cone photoreceptors.
The responses of individual salamander L-cones to light steps of moderate intensity (bleaching 0.3-3% of the total photopigment) and duration (between 5 and 90 s) were recorded using suction electrodes. Light initially suppressed the circulating current, which partially recovered or "sagged" over several seconds. The sensitivity of the cone to dim flashes decreased rapidly after light onset and...
متن کاملLight-dependent ion influx into toad photoreceptors
To measure the influx of Na+ and other ions through the light-dependent permeability of photoreceptors, we superfused the isolated retina of the toad, Bufo marinus, with a low-Ca2+ (10(-8) M), low-Cl- Ringer's solution containing 0.5 mM ouabain. Under these conditions, the membrane potential of the rod is near zero and there is no light-induced potential change either in the rod or in more prox...
